[QUESTION] How are your routers tested for quality control for refurbishing?

[ANSWER] We physically plug in the devices, connect them to the internet and make sure they route without problems. The flashing process itself (via serial cable) reveals Memory issues if any, and any bad memory blocks outside of the norm are noted through simple NAND Commands or Flash Commands. LAN ports are tested by packet loss tests through connected laptops. Wifi is tested by connecting to them and testing for normal activities and throughput speed tests. Most all routing problems are driver or outdated firmware related so we make sure and always use after market stable firmware releases unless otherwise asked for different. This works out better for everyone to flash more powerful firmware. Juice up your router!
